Hence, public agencies can take advantage of this fact by creating communication channels with society. This paper presents the SocialSupervisor, a geographically enhanced social content site, where citizens can be notified about public works nearby. Moreover, they are able to post complaints related to any irregularity in

Ten Lessons Learned from Integrating Interaction Design and Agile Development

2013 Agile Conference, 2013

Therefore, integrating these two areas becomes a challenging task. There is little guidance about integrating them. Very limited empirical evidence exists on Agile development and Interaction Design being combined in practice. In order to better understand how these approaches are combined in practice, a multiple-case study of Agile teams working with Interaction Designers was performed. In the paper, we present a set of ten lessons learned from these studies.

User-Centered Design and Agile Methods: A Systematic Review

It shows that a common process model underlies such approaches and discusses which artifacts are used to support the collaboration between designers and developers.

User Experience Design and Agile Development: From Theory to Practice

Journal of Software Engineering and Applications, 2012

We performed a field study in an ongoing project of a medium-sized company in order to check if the proposed framework fits in the real world, and how some aspects of the integration of UX and Agile work in a real project. This led us to some conclusions situating contributions from practice to theory and back again. The framework is briefly described in this paper and consists of a set of practices, artifacts, and techniques derived from the literature. By combining theory and practice we were able to confirm some thoughts and identify some gaps-both in the company process and in our proposed framework-and drive our attention to new issues that need to be addressed. We believe that the most important issues in our case study are: UX designers cannot collaborate closely with developers because UX designers are working on multiple projects and that UX designers cannot work up front because they are too busy with too many projects at the same time.

A novel virtual world based HCI paradigm for multimedia scholarly communication

However, the need to process huge amounts of data in scientific analysis and communicate its results to the scientific community has presented a big challenge for researchers in the data-intensive era. In addition to providing accurate and flexible graphical representations of data, the entire research process should ideally be made verifiable by peers. While web-based tools have been ...

Myelin Lipids Inhibit Axon Regeneration Following Spinal Cord Injury: a Novel Perspective for Therapy

Molecular neurobiology, Jan 13, 2015

Here, we used shiverer (shi) mice to assess axon regeneration following spinal cord injury in the presence of MAIs and CSPG but in the absence of compact myelin. Although in vitro shi neurons displayed a similar intrinsic neurite outgrowth to wild-type neurons, in vivo, shi fibers had increased regenerative capacity, suggesting that the wild-type spinal cord contains additional inhibitors besides MAIs and CSPG. Our data show that besides myelin protein, myelin lipids are highly inhibitory for neurite outgrowth and suggest that this inhibitory effect is released in the shi spinal cord given its decreased lipid content. Specifically, we identified cholesterol and sphingomyelin as novel myelin-associated inhibitors that operate through a Rho-dependent mechanism and ha...

The importance of ether-phospholipids: A view from the perspective of mouse models

Biochimica et Biophysica Acta (BBA) - Molecular Basis of Disease, 2012

Plasmalogens are the most abundant form of alkenylglycerophospholipids, and their synthesis requires functional peroxisomes. Defects in the biosynthesis of plasmalogens are the biochemical hallmark of the human peroxisomal disorder Rhizomelic Chondrodysplasia Punctata (RCDP), which is characterized by defects in eye, bone and nervous tissue. The generation and characterization of mouse models with defects in plasmalogen levels have significantly advanced our understanding of the role and importance of plasmalogens as well as pathogenetic mechanisms underlying RCDP. A review of the current mouse models and the description of the combined knowledge gathered from the histopathological and biochemical studies is presented and discussed. Further characterization of the role and functions of plasmalogens will contribute to the elucidation of disease pathogenesis in peroxisomal and non-peroxisomal disorders. This article is part of a Special Issue entitled: Metabolic Functions and Biogenesis of Peroxisomes in Health and Disease.
